How To Machine Ceramic Parts

Following a final firing when as fired tolerances are not sufficient fine diamond machining grinding using diamond impregnated cutters is often required.

How to machine ceramic parts.

Conventional machining methods milling drilling turning may be applied for the ceramic parts in the presintered state. Manufacturing tolerances between 002 and 010 inches are possible with this process. While there is a learning curve to machining macor it is certainly achievable with the correct skill and patience. Ceramic parts may be effectively machined before the final sintering stage either in the green non sintered powder compact state or in the presintered bisque state.

Superior has in house capabilities to design engineer tool and manufacture these advanced ceramics in quantities ranging from one prototype part to large. Properties and considerations of manufacturing by ceramic mold casting. Macor machining guide how to machine macor. Manufacturing by ceramic mold casting is similar to plaster mold casting in that it can produce parts with thin sections excellent surface finish and high dimensional accuracy.

Corning is well know for its glass products and macor is a hybrid machinable glass ceramic that can be fabricated into intricate shapes with tolerances on the order of 0 0002 in with ordinary carbide tooling. Additionally materials like silicon carbide sic may not fit the precise definition of a ceramic material but they can still be classified as part of the ceramic family. Today s business comprises a host of custom ceramic parts made from alumina zirconia zirconia toughened alumina steatite mullite cordierite grade a lava macor and boron nitride. Many people are woefully unaware of just how prevalent ceramic parts are in the industry.

Ceramic is highly prized for its thermal resistance toughness and applications in the electrical field. Macor is one of the few ceramics that can be machined using regular metal working tools. Fine diamond machining full density parts ceramic parts fired to their full density are too hard for machining with tool steel cutters or even conventional methods. Everything from electrical insulators to use in high powered lasers and even as durable nozzles for dispensing materials from.
